1.1.1 The ENIAC
Before the EDVAC was finished, several other machines were built that incorporated elements of the EDVAC design of Eckert, Mauchly, and von Neuman. One was the Electronic Delay Storage Automatic Computer, or EDSAC, which was developed in Cambridge, England. It first operated in May of 1949 and is probably the world’s first electronic stored-program, general-purpose computer to become operational. The first computer to operate in the United States was the Binary Automatic Computer, or BINAC, which became operational in August of 1949.
在ENIAC的研制中，一个天才的数学家Von Neuman(冯.诺伊曼)加入 到 Eckert和Mauchly团队,他们一起提出了储存程序计算机的主意。这部 机器被称做电子离散变量自动计算机, 或简称EDVAC,是第一部包括了计 算机所有特征的机器。然而,直到1951年，它一直没有完成。
